Hand of the Red Sun

"The Hand" is an increasingly popular fear name coined for them

The largest and most violent band of Red Sun cultists.

They are regarded as a high-value terrorist organization.

Complete clusterfuck.

Literally every reasonable human being that knows about them.

Reaping power for their sect(s) by any means necessary, including attacking the world's most renowned defenders, with the end goal of getting the Red Horde to win.

Large arsenal of firearms, stolen arkura and improvised explosives.

As of 2267 they have started getting a hold of mil-spec equipment, likely with the aid of a Seer's mind-influencing powers.

They leave bloody handprints where they've struck.
